These tests are for screening. A result is not a diagnosis: only a psychiatrist or psychologist can make one, after talking with you.
Your answers are scored on this device and never sent. Only your result is saved, with the email address you confirm.
Confirm your email address
Before the test we send a 6-digit code to your email address. Your result is saved with it, so that our team can help you if you wish. The email with the code contains no health information.
The questions below are about your eating habits. For each one, choose the option that suits you best.
Choosing an answer takes you to the next question. You can go back at any time.
Your result
Orthorexic tendency
Your score is below the limit (40) that the authors of the scale proposed for an orthorexic tendency. This may mean that thoughts about healthy eating take up an important place in your life; however, the scale can overstate this tendency, so the result on its own says little. If your food rules make you anxious, limit your social life or lead to weight loss, it would be good to talk to a professional.
No marked orthorexic tendency
Your score is above the limit the scale uses for an orthorexic tendency. Your answers suggest that thoughts about healthy eating do not stand out to the point of restricting your life.

Take your result as a rough guide, not a diagnosis. How you feel over time, and a conversation with a specialist, tell much more than a questionnaire.
Talk it through with a specialist
If your result worries you, or you would like to talk it through, our psychiatrists can review it with you, free and without obligation.

About this test
Orthorexia is an obsessive focus on healthy or “correct” eating that starts to restrict a person’s life. The ORTO-15 is a 15-question scale developed in 2005 to assess this tendency, and it takes about 4 minutes. Scores range from 15 to 60; a low score indicates an orthorexic tendency. The result is not a diagnosis.
